Claims.

The present invention relates to a stamp, label or strip feeding and gluing mechanism and more particularly to such a mechanism for use in applying a stamp, label or strip to a pre-determined portion or end of an article or package. In prior devices of this character with which applicant is familiar, the erroneous withdrawal of more than one stamp, label or strip from the feed magazine or stack is rather commonly encountered. "Ihis erroneous feeding of more than one strip at a time interferes with the proper operation of the feeding mechanism, the gluing mechanism and the package applying mechanism, and represents a considerable loss of money in the destruction of tax stamps when employed for the feeding and applying of taxstamps to packages such as packages of tobacco. Another rather common failure of such prior devices is the failure of. the withdrawing mechanism to withdraw a stamp, label or strip from the magazine, and this failure of the withdrawing mechanism means that packages are rather commonly passed through the wrapping machine without having a stamp, label or strip attached thereto, and such packages must either be refed .through the wrapping machine or else discarded entirely.

Other difficulties encountered in feeding the strips pastthe gluing mechanism or rollers are due to the tendency of the stamps, labels or strips to adhere to the glue rolls or for other reasons to be torn or mispositioned in their feeding mechanism as they are brought into or past thegluing mechanism, this resulting in the destruction of the stamps, labels or strips, or the mispositioning of the same upon the article or package.

It is accordingly an object of this invention to provide a mechanism for feeding stamps, labels or strips from a magazine or stack to a predetermined position for association with an article or package, and during such feeding to apply adhesive thereto, which mechanism is simple in construction and avoids the defects and insufficiencies of the prior devices.

The claims presented in the present case re late essentially to the glue applying means, and to the mechanisms and strip feeding means more intimately associated therewith. Claims to the hopper structure for the strips, and to the mech anisms and feeding devices more directly assoriated therewith are presented in a divisional application. 4

Among the more specific objects relating to the glue applying means and associated mechanisms is to provide in a stampfeeding and adhesive applying mechanism a gluing' device having stamp feeding means separate from the gluing means and in which the glue cannotpass to or accumulate upon the feeding means. I It is also an object of the invention to provide in a feeding and gluing mechanism a glue applier between which and the stamp, label or strip there will be no relative motion during the application of the glue to the stamp and in which feeding means are provided forwithdrawing the stamp, label or strip from'the glue applier in a direction and'at a speed such that the glue ap plier will exert no retarding eifect on the feeding of the stamp, label or strip. A still further object of the invention is to provide improved gluing mechanism for applying glue or adhesive to stamps, labels, or'strips', and to provide in combination therewith improved feeding means whereby to propel the stamps, labels, or strips through the gluing mechanism in a proper and reliable manner.

Other and further objects and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawings wherein; f

Fig. 22 is a fragmentary view in vertical 'eleva tion taken substantially along the line 22--22 of Fig. 1, with a portion of the stamp supplying magazine and one suction head being broken away for purposes of illustrtaion.

As shown in the drawings, the frame or. base of the machine is provided with an upstanding web 2 (Figs. 1, 3 and 5) to which is secured as by screws 4 the rear wall plate 6 of a hopper or magazine 8. The hopper 8 comprises in addition to the'rear plate 6 a pair of plates l0 generally L-shaped in cross section and secured .to the opposite vertical edges of the plate 6 as by the screws 12. The plates I6 form he sides and the open front wall of the magazinet. The inner wall surfaceof therear. plate 6 is tapered or bevelled inwardly as at. M to facilitate the manual insertion of relatively elongated stamps, ,la bels or similar strips such as may be desired to aply to articles or packages.

In, which flanges-form the open front of the magazine, in a downward direction tapers outwardly as shown in Fig. 2 to permit outward deflection of a flexible strip 18 secured to the flanges lfieadjacent the upper edges as by rivet 20. The strips l8 provide deflectable wall surfaces for accommodating stamps which vary in width within the usual tolerances permitted in the production of such stamps so that the stamps of greater width will not be marred or torn when being moved between two unyielding surfaces spaced apart a distance less than the width of these wider stamps, and atthe same time means 'are provided for preventing sidewise shifting of the stamp in the stack within the magazine. The strips I8 also provide means for yieldablymounting. a pair of stamp Supporting blocks 22 riveted or otherwise secured to the loweredges of the strips 18. Each of the blocks 22 is urged in an inward direction by a ,coil spring 24 acting on the block 22 through a bowed strip 25 secured or fulcrumed at its upper end to. a flange l6 by "a pin 28 and pressing at its lower end against the block 22. Each spring 24 iscarried by a pin 30 passing throughthe strip 26 and secured to the flange Hi, the spring 24 being interposed between the strip 26 and a tension adjusting screw 32 on the pin 39. A similar pair of stack-supporting blocks 34 are rigidly secured to the bottom of the rear wall plate Gas by screws 36 and are aligned with the stack-supporting blocks 22. The inner surfaces of the. stamp-supporting blocks 22 and ,34 are serratedas at 33 to facilitate bowing ofthe end portions of the bottom stamp under the action of the stamp withdrawing means as seen in Fig. 20, to cause fluttering of a second stamp in the stack which, during withdrawal of the bottom stamp may tend to adhere to the latter, thereby'to break the second 7 The inner surfaces I of each inwardly directed flange I6 of the plates a pair of auxiliary stack-supporting pins comprising pointed set screws 40 (Fig. 22) adjustably mounted in the side forming flanges of the plates 10 a given distance above the blocks 22 and 34. The set screws 40 are held in adjustable position by clamp nuts 42. The pointed ends of thepins or set screws 40 project between the ends of certain adjacent ones of the stamps in the stack and support the stack of stamps thereabove; The weight of the stack of stamps above the pins 40 causes the stamps immediately above the pins to sag centrally as shown in Fig. 22, and as stamps are withdrawn from below the pinsf the weight of the stamps causes these sagging. stamps to pass the pins 40. The pins 40 also act to prevent the'application of the weight of the stack tothe opposite end portions of the stamps below and thereby facilitate bowing of the opposite end portions of the bottom stamp when the same is withdrawn from themagazine.

The stamp withdrawing or removing means preferably comprises a pair of suction heads or blocks 44 (Figs. 1, 4, 5, and 20 to 22) the blocks having concave upper stamp engaging surfaces 46 (Fig. 5) and being spaced apart to engage the opposite end portions of the stamps as seen in Figs. 4 and 22. The suction heads 44 are mounted on the outer ends of parallel levers 48 which at their opposite ends are journalled on a stud shaft or bolt 50 (Figs. 1 and 5) and secured to operating yoke 52, also journalled on the stud shaft or bolt 50. The stud shaft 58is mounted in a boss 54 (Fig.1) formed on the web 56 of the frame portion 58. The yoke 52 is oscillated to move the suction heads between the stamp feed magazine 8 and a stamp receiving and guiding plate 60 (Figs. 1, 3, 5, 6, 7, 8, 13, 14 and 21) by an operating link 62 (Fig. 5) driven by any suitable and convenient mechanism in proper time elation to the feeding mechanism subsequently to be described, which feeds the stamps along the plate 60.

Air is supplied to and withdrawn from the vertical openings 64 in each suction head through a transverse port 65 in the suction head and a longitudinally extending port or passage 68 (Figs. 10 and 22) in its mounting lever 48. The longitudinal port or passage 68 at its inner end cominunicates with a transverse suction port or passage i0 and by a vertical passage?! with a transverse suction breaking port or passage '14. Connection of the suction port 10 to a vacuum pump or vacuum source not shown-and the connection of the suction breaking port or passage 14 to the atmosphere is controlled by a valve mechanism 16 (Fig. 11) which comprises a lever 18 (Figs. 1, 5, 11 and 16 to 19) extending parallel to each lever 48 and interposed between its associated lever 43 and a connectingblock to which the source of vacuum is connected as by the flexible pipe or tube 82. Each lever 18 is journalled at one end on the stud shaft 50 and adjacent its other end is provided with a transverse port or passage 34 (Figs. 1 1. 18 and 19) which when the lever 48 is moved to the position shown in Fig. 18 connects the suction port '10 to the port or passage 85 which latter port is connected to the suction pipe 82 by the port or passage 88. The connecting block 88 ismounted on the spaced pins 90 ass-2:554

The screw 98 is carried by a plate or bracket I02 secured'to or formed upon a post or bar I04 se cured to any suitable fixed portion of the machine frame. Each valve lever 18 is also provided with an upwardly projecting lug I06 which is adapted to engage an adjustable stationary set screw or bolt I08 (Fig. 1'7) as its associate lever approaches its upward limit of movement to cause relative movement between these levers to bring them into the position shown in Fig. 18, wherein as previously described the suction port .Iflis connected by the valve port and the ports in the confne'cting block80 to the suction intake. pipe 82. The controlling set screw I00 for the valve lever J8} shown at the lower portion of Fig. 1 .is carried byfthe inwardly turned end IIO .(Figs 1 and 17) of the post I04, while the controlling set screw for the othervalve lever .18 is carried by the bracket [12 fastened to the web 56 of the machine frame. 1 Cooperating with the suction heads 44 towithdraw the lowermost stamp from the stack, are a stamp-straightening andstack supporting bar I I4 and stacksupporting fingered I6 (Figs.1, 3, ,4, and 22). The stamp straightening and stack supporting bar- I I4 moves upwardly and downwardly with thesuction heads .44 and for that .purposeis secured atone end to the operating 0 y ke-5 a b aim n ing ew a andjusting set screw I20 carriedby the bar ,I,-I4; so that the bar may be adjusted relative to the yoke properly to position the opposite end of the. bar relative to the aligned-concave surfaces 46 of the suction heads. The lowermost stamp both by reason of the weight of its unsupported portion between the opposed sets ofsupportingblocks 22 and 34 and by;reason of the weight of the superposedstack ofstampstends to sag. It requires .a .-much greater force to effect the bendingor bowing of an elongated stamp or strip. which is cuved or bent longitudinally .thanis required to ubendorbow astamp whichlies 'fiatina' longitudinal plane. Therefore such sagging: of, the stamp tends to prevent the withdrawal of. the stamp under the action of the concave suction "headsxWhen the suction heads '44 are brought gagement with the concave surfaces of the suctionheads.

The stack supporting fingers I I6 project inwardly from opposed'bars I22 (Figs. 3, 5 and 22), extending vertically on opposite sides'of the magazine 8; each bar I22 being adjustably mounted withinan elongated'recess or groove I24 (Fig. 3) of a lever I26. The levers I26 are secured at their upper ends to stud shafts I20 and I 30 (Figs. 1, 3 and 5), journalled in bosses I32 formed on the web 2' of the machine frame. The-shafts IZBand I30are interconnected for simultaneous oscillation in opposite directions by alink' I34 (Figs. land 3) pivotally secured at its opposite ends to oppositely extending cranks I36 and I 38"secured respectively to the stud shafts I28and I30. Operation of the shaft I30 and consequent simultaneous operation of the shaft I28 'is'effected by driven'link I 40 pivotally connected to the outer endof a crank I 42securd to the shaft I30, the linkbeing driven by any suitable mechanism in proper timed relation to the link 62 (Fig; 5) so that the stack-supporting fingers I I6 will be moved inwardly to pro- J'ect between the concave end portions of the stampbeing withdrawn and the next stamp in the stack as shown in Fig. 4; thereby to remove the weight of the stack from the stamp being removed to'insu're that the lowermost stamp will be withdrawn by the suction head and to prevent withdrawal of a second stamp which might tend toadhere to the stamp being withdrawn in 'a region between the suction heads.

' It should be noted that in being withdrawn from the stack, the stamps pass across the serrated surfaces 38 of the stack-supporting blocks 22 and 34, and these serrated surfaces will'cause the edges of the stamps to flutter, which fluttering action will-separate theup er stamp from a lower stamp if the opposite ends of two' stamps are simultaneously sucked onto the suction. heads so that the stack-supporting fingers pass between the second and'third stamps of the stack, rather than between the'first and second stamps of the 'stack.= The serrated surfaces also, following separation of'the second stamp from the stamp being properlyfedyby engagemenfwith the edges "of the stamp (as shown'in Fig. 15) retain-the stamp, thereby mainta-iningfthe' stamp "fiat or straight during this movement of the stamp from the stack to the stamp receiving and guiding plate '60, and preventing the sagging of thestamp and the consequent release from the suction hea'ds'i The bar II 4 as it 'moves downwardly 'pass'es at'its forward edg'e through a'recess I44 The suction'heads 44 and the bar H4 deposit the stamp on an upper surface 0 1 the p1a'te'60 in the path of movement of a pair ofpusher' bars (Figs. 1, '7 and 8) in the'forwar'd edge "ofthe or feed fingers I 46 (Figs.

H

From the pusher bar I46 each stamp is re, ceived and fed in an arcuate path past the glue rollers by a pair of star wheels 220 (Figs 3, 6,-{l and 13), secured to the shaft I10 and. driven thereby at substantially the same peripheral speed as the rollers I68. The stamps will there;- fore be fed in this arcuate path without move} ment relative to the periphery of the glue rollers so that there will be no retarding or speeding up of the stamps by the glue rollers, and there will be no piling up of adhesive adjacent one or the other edge of the stamp or any flowing'ofthe adhesive around an edge of the stamp onto its outer surface. The pusher bars I46 feed the stamps to a position on the plate 60 in the path of movement of the radially projecting lugs 222" of the star wheels 220, the plate 60 being slotted to permit the star wheels 220 to pass. therethe stamp during its feeding movementto the star wheels'and to the forward wall portion 223 (Fig.3) along which the stamp is fed vertically V The covers I 98 also overlie the star wheels 220 in spaced relation to the plate60 and are recessed to receive the feeding lugs 222 of the star wheels. The star wheels 220 feed the stamps into the path of movement of av pair of vertically shiftable pusher bars or feed fingers 224 (Figs. 3, 5, 7, 8, 13 and 14) which pass through-slots 226 in the outer end walls of the covers I98 and grooves2 28' in the outer end walls 204' of theglue pot to move the stamps from the star wheels 220*along avpath extending tangentially to the peripheries of the glue rollers I68. The pusher bars or feedfingers 224 are secured at their upper ends to an arm 230 (Figs. 1, '3 and 5) in turn secured to a block 232 as by an angle iron 234, the block 232 being in turn fastened to an operating rod 236 slidably mounted in the spacedjhorizontal arms 238 of the bracket 240 fastened to the web 2 of the machine frame.

27.3 1 5: age and to fold, the ends of the stamp into'ad package, r r. r a f The operation of the illustrated stamp feeding and gluing mechanism will be apparentfrom the foregoing description' Such operation may, however, be briefly summarized as follows:

As the suction heads 44 are moved upwardly hering V engagement opposed sides 'of Q the and downwardly to withdraw the lowermost stamp from the stack of stamps in the magazine 8, the horizontal pusher bars or feed fingers I46 move forwardly and backwardly to feed the previously withdrawn stamp to the star wheels 220. When the suction heads 44 reach their lowermost positionand deposit the withdrawn stamp on the receiving and guiding plate 60, .the pusher bars I46 moveforwardly from their rearmost position to engageand feed the stampto the star wheels 22!] as previously stated. Dur-. ing upward and downward movement of thesuction heads, the adjustable screws '98 and I08 engage the lugs of the valve levers l8 and cause relative movement between these valvelevers and the levers 48 so as to connect the suction heads to the source of vacuum when the levers 48 reach their upper position and to connect the suction heads to atmosphere when the levers 48 reach their lowerfpositions. Y e

The lugs 222 of thestar wheels 2,20 engage the stamps and, feed them in an arcuatepath con centric tovthe .axis of the glue rollers and at a speed substantially equal to;the peripheral speed of the glue rollers sothat during application of adhesive to the stamps; there is no relative movement between the stamps and the glue rollers. It; should be noted that the stamps are fed to the glue rollers along a path extending tangentially to the peripheriescf the gluerollers so that there will be no warpingof the stamps by the rollers, nor accumulation of excessive adhesive at the forward edges of the stamps. As the star wheels move the stamps aboutthe arcuate path concentric to the axis ofthe glue rollers, the vertical pusher bars or feed fingers .224 descend and feed the.- stamps from the star wheelsalong a vertioalpath tangentially to the peripheries of Y the glue rollers and onto a table 244 along which packages 246 are advanced to receive the stamps. The manner in which thestack-S Dmrtin a d stamp-straightening bar I I4 and the stack-supporting fingers I I6,"the serrated stack-supporting blocks 22 and 34 cooperate with the concave heads 44 to insure the withdrawal of a stamp upon each downward movement of the suction head and to prevent withdrawal of more than one stamp at a time from the magazine 8 has been previously described and neednot berepeated. Changes may be made in the form, construe tion and arrangement of the parts without departing from the spiritof the invention orsaorificing. any of'its advantages, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claims. 7
